问题 Instead of retrieving a single row of data from my store, how can I modify the following code to retrieve all records? var store = Ext.data.StoreManager.lookup('MyStore'); store.setProxy({ type: 'pagingmemory', data: store.getAt(0) }); store.load(); Any thoughts? 回答1: You can use store.getRange() or you can use store.data.items .

问题 I know that this question has been asked quite a few times, but I could not find anywhere a final resolution; so here goes: How do you store an IP (both IPv4 and IPv6) using best-practice, within a DB, without knowing the DB?

问题 I need a way to store a list of method pointers, but I don't care about what class they belong to.

MethodPointer mp = ... // call the method (mp.object->*method)(); ... } This obviously doesn't

问题 So the code I'm using is at http://jsfiddle.net/8j947/10/ and it returns a value of true or false for the variable isLive. How can I use the variable onLive in a later function? I read the answers at Accessing variables from other functions without using global variables, but I'm having a lot of trouble getting it to work. All I want is to store the value, true or false, so I can call it into an if statement in a later function. Can anyone give me the simplest way to do this? Is there a way

问题 I am trying to integrate Facebook to one of my projects. At this time I have successfully integrated Twitter so users can update their status while they are on my website. There is a one-time login to Twitter and then I store oauth_token, oauth_token_secret, user_id and screen_name so when they login to my site (via my own login), they do not need to login to Twitter again. And now, I want to do the same for Facebook. How can I let users connect Facebook to my site and update their status any

问题 I am trying to create a Tkinter program that will store an int variable, and increase that int variable by 1 each time I click a button, and then display the variable so I can see that it starts out as 0, and then each time I click the button it goes up by 1.
